Introduction Glochidia with and without tissue Previous studies show there might be a distinction Photo taken by Dr. Mill operator

Slide 5

Previous Studies Spotfin shiner, basic shiner and hornyhead chub are host fish Golden shiner and rivulet chub are minor host fish From 2003 Host Fish Suitability Trial

Slide 6

Previous Studies 2003 Study, glochidia without and with tissue as life cycle stages

Slide 7

Goals Find which host fish is measurably more grounded: hornyhead chub or basic shiner Find new host fish Study glochidia without tissue and with tissue as life cycle stages

Slide 8

Procedure Collect host fish and mussels from St. Croix River Infest fish with glochidia and check siphonate at regular intervals Fish in measurable study kept in individual aquaria

Results Table 1: Percent Transformation for hornyhead chub and spotfin shiner

Slide 14

Conclusions Common shiner, emulate shiner, blackchin shiner and longnose dace are host fish Not ready to decide distinction between glochidia without tissue and with tissue It creates the impression that related fish have the same mussel

Slide 15

Practical Applications Results of the factually more grounded host fish could be utilized to reintroduce the Round Pigtoe mussel by making bringing mussels up in a research center setting more productive By finding that related fish have the same mussel, host reasonableness trials can be rearranged

Slide 16

Future Studies Repeat the study with numerous types of fish from the same family Conduct a Histological study with pictures of mussels at various life cycle stages to deterimine if glochidia without and with tissue are separate life cyce stages
